Improvement in machines for cutting lath-bolts



UNITED STATES PATENT Orrion THOMAS CRISPIN, or BAY CITY, MICHIGAN.

Specification forming part of Letters Patent No. 118,205, dated August22,1871.

To all whom it may concern.-

Be it known that I, THOMAS ORISPIN, of Bay City, in the county of Bayand State of Michigan, have invented certain Improvements inLath-Bolters, of which the following is a specification:

This invention relates to an improvement in lath bolters; and consistsin certain arrange ments and combinations hereinafter more fullydescribed and claimed.

Figure l is aside elevation of a machine embodying my invention. Fig. 2is a top and longitudinal view of the same. Fig. 3 is a side andelevated view of the cam or upright, showing one of the rollers orshears at the top.

Fig. 1 is the driving-pulley, from which motion is communicated to theoperating parts. A is the saw by whichthe timber is to be out. ()n thetail end of the mandrel upon which the saw is hung is a irictioirpulley,B. Directly under said pulley B is a friction-wheel, C, hung on a shaft,one end of which is supported on a movable bridge-tree, F, said wheel 0being thrown in and out of gear with pulley B by the lever 0, said leverbeing supported on the fulcrum P and connected to the bridge-tree F bythe rod N. ()n'the same shaft with wheel 0 is a pulley, E, from which abelt, Gr, runs to the crank-wheel H. To the crank I is attached thepitman J,

' connecting with the cam or upright K. On the top of said upright istwo rollers or sheaves, one of which is shown at It, Fig. 3, and whichpasses up between the friction-irons M M, underneath the carriage.

The operation of the machine is as follows: The material to be out isplaced upon the carriage, and the gauge adjusted to give the properthickness, when,a rotating motion being given to the saw A, areciprocating movement of the carriage is produced through thefriction-roller B, pulleys O and H, crank 1, and connections J K R. Thematerial may be moved upon the carriage by band or by any of theautomatic devices in common use for similar purposes.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of pulley H, crank I, connections J K, roller R, andfriction-plates M, attached to the carriage, all constructed as and forthe purpose specified.

2. The lever Q, fulcrum P, rod N, and lever F, in combination with thefriction-pulleys O B and saw-mandrel, as for the purpose hereinbcforeset forth. A
